Micronaut - 不存在 [io.micronaut.transaction.SynchronousTransactionManager] 类型的 bean

如何解决Micronaut - 不存在 [io.micronaut.transaction.SynchronousTransactionManager] 类型的 bean

我正在将我的一个微服务从 Spring 迁移到 Micronaut，这是我在调用控制器加载一个实体时面临的一个问题。我得到的错误是：

{
    "message": "Internal Server Error: No bean of type [io.micronaut.transaction.SynchronousTransactionManager] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor)."
}

我已经启用了 io.micronaut.context.condition 记录器，将其设置为 TRACE 级别，但我在日志中没有看到类 SynchronousTransactionManager 的引用。

这是我的 build.gradle：

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
        maven {
            url 'https://jitpack.io'
        }
    }
    dependencies {

这是我的application.yml

控制器：

@Controller
@Secured(SecurityRule.IS_AUTHENTICATED)
public class GymController extends BaseController
{
    private final GymReconstructionService gymReconstructionService;
    private final PatrimonyMapper patrimonyMapper;

    @Inject
    public GymController(
        GymReconstructionService gymReconstructionService,PatrimonyMapper patrimonyMapper
    ) {
        this.gymReconstructionService = gymReconstructionService;
        this.patrimonyMapper = patrimonyMapper;
    }

    @Get("/gym/upgrade/estimation")
    public HttpResponse<ReconstructionEstimation> getUpgradeReconstructionEstimation() {
        return HttpResponse.ok(gymReconstructionService.getUpgradeEstimations());
    }
}

应用服务

@Singleton
@Transactional
public class GymReconstructionService extends ApplicationService
{
    private final GymRepository gymRepository;
    private final DebitMoneyClient debitMoneyClient;
    private final LoggedUser loggedUser;

    @Inject
    public GymReconstructionService(
        GymRepository gymRepository,DebitMoneyClient debitMoneyClient,LoggedUser loggedUser
    ) {
        this.loggedUser = loggedUser;
        this.gymRepository = gymRepository;
        this.debitMoneyClient = debitMoneyClient;
    }

    public ReconstructionEstimation getUpgradeEstimations() {
        var gym = getGym(loggedUser.getClubId());

        return gym.getUpgradeReconstructionEstimation();
    }
    private Gym getGym(UUID clubId) throws GymNotFoundException {
        return gymRepository
            .findById(clubId)
            .orElseThrow(GymNotFoundException::new);
    }
}

我意识到的一件事是，如果我删除 @Transactional 注释，则不会再发生此错误，但最终会出现另一个错误：

{
    "message": "Internal Server Error: No backing RepositoryOperations configured for repository. Check your configuration and try again"
}

这里有什么关于发生了什么的线索吗？

解决方法

我已经解决了类似的问题。
